Description Mark Wielaard 2008-03-25 10:42:20 EDT
When inside a plt entry jump slot you cannot always get reliably backtrace on
x86_64 until you are outside the plt entry itself (and into the shared library
function).  Although you cannot easily step into a plt entry currently, it can
happen that a backtrace is captured just at the moment one thread is inside a
plt entry. In that case a single entry backtrace is produced instead of a full
backtrace.

Upstream has patches for stepping into (all architectures) and producing full
backtraces from plt entries (x86_64):
